Screening Stocks for High Amplitude, Volume, and Weekly Trend Reversals

Summary

The document outlines a Chinese stock screen that combines daily amplitude above 1, current trading volume above 10,000 lots, a higher opening price than the previous close, and a weekly close crossing above its 30-week moving average. These filters are intended to find actively traded, volatile stocks showing a possible shift toward an upward trend. It also suggests adding other technical measures and company fundamentals, including valuation and profitability metrics, and checking multiple chart intervals.

The article provides indicator and Python examples but no backtest or performance evidence. Its own caveats are that the rules omit fundamental and broader market risks, may make the candidate pool too narrow, and rely on a weekly signal that can be poorly suited to fast-moving short-term markets. The code examples also do not clearly demonstrate every stated condition, so the screen should be treated as a proposed filter rather than a validated strategy.

Key ideas

• The screen selects stocks with amplitude above 1, volume above 10,000 lots, a higher open than the prior close, and a weekly close crossing above the 30-week average.
• The rules target volatile, liquid stocks with a potential upward trend signal.
• The article proposes adding technical indicators, fundamental measures, and signals from other timeframes.
• It provides code examples but no evidence of historical or live performance.
• Weekly signals may lag or be unsuitable for fast short-term trading.
